To find the standard enthalpy change (Δ_rH) for the reaction: \[ \text{OF}_2(g) + \text{H}_2\text{O}(g) \rightarrow \text{O}_2(g) + 2\text{HF}(g) \] we will use the bond energies provided for the calculation. The formula for the enthalpy change in terms of bond energies is: \[ \Delta_rH = \text{(Bond Energy of Reactants)} - \text{(Bond Energy of Products)} \] ...
